Introduction and Specifications

Finally AMD gets a PCIe motherboard and SLI support. What can you expect from the Asus A8N-SLI Deluxe as a mainboard solution?

Note: You may also want to read our review of the Asus A8N32-SLI as it is the updated version of this board with a newer chipset and passive cooling.


NVIDIA’s SLI technology has been hyped enough already, so I won’t get too much into that here again, just to say that SLI is what a lot of our readers have been waiting for since its announcement months ago.  The Asus A8N-SLI motherboard is the first motherboard to reach my testing lab to support this new multi-GPU technology and so it has a lot to live up to, not to mention that the standard motherboard analysis has to be done on the product as well. 

We’ll start off with the Asus board specs:
